The aim of this study was to reveal correlation between Doppler in the fetal middle cerebral artery and fetal decompensation during labor in uncomplicated pregnancies at 40 weeks and beyond. We by means of ultrasound Doppler examined 260 women at 40 to 42 weeks of uncomplicated pregnancy 48 hours before delivery, with fetal condition assessed subsequently during labor and immediately after delivery. We found out that in the group of women with caesarean section caused by fetal distress during labor, pulsatility indices in the middle cerebral artery evaluated just before labor were significantly lower than in the group of women whose fetus had better condition during labor. The same trend was observed when comparing Doppler velocimetry using the fetal cerebroplacental ratio. Moreover, we identified that in the group of women with newborns having Apgar 7 and less, middle cerebral artery measured less than 48 hours before delivery were lower than in the group of women having babies in better conditions. Furthermore, as result of this study, the trigger threshold for PI was found to be 0.835, below which fetuses have adverse perinatal outcome during labor. Thus, it was shown that Doppler in the fetal middle cerebral artery in uncomplicated pregnancies at 40 weeks and beyond could predict fetal distress and avoid hypoxic brain damage to the fetus during labor.

The Impact

Background: Middle cerebral artery division (M2) occlusion was significantly underrepresented in recent mechanical thrombectomy (MT) randomized controlled trials, and the approach to this disease remains heterogeneous. Objective: To conduct a systematic review and meta-analysis of outcomes at 90 days among patients undergoing MT for M2 middle cerebral artery (MCA) occlusions. Methods: Five clinical databases were searched from inception through September 2016. Observational studies reporting 90-day modified Rankin Scale scores for patients undergoing MT for M2 MCA occlusions with an M1 MCA control group were selected. The primary outcome of interest was good clinical outcome 90 days after MT of an M1 or M2 MCA occlusion. Secondary outcomes of interest included mortality and excellent clinical outcome, recanalization rates, significant intracerebral hemorrhage, and procedural complications. Results: A total of 323 publications were identified, and 237 potentially relevant articles were screened. Six studies were included in the analysis (M1 = 1,203, M2 = 258; total n = 1,461). We found no significant differences in good clinical outcomes (1.10 [95% CI, 0.83-1.44]), excellent clinical outcomes (1.07 [0.65-1.79]), mortality at 3 months (0.85 [0.58-1.24]), recanalization rates (1.06 [0.32-3.48]), and significant intracranial hemorrhage (1.19 [0.61-2.30]). Conclusions: MT of M2 MCA occlusions is as safe as that of main trunk MCA occlusions, and comparable in terms of clinical outcomes and hemorrhagic complications. Randomized clinical trials are needed to assess the impact of MT in patients with M2 occlusions, given that M1 MCA occlusions have different natural histories than M2 occlusions.

Background: IUGR is a most common and complex problem in modern obstetrics. Most commonly use methods to assess fetal condition are BPP and NST which are not sensitive for predicting better perinatal outcome.  Present study was an effort to evaluate the role of ratio of pulsatility index (PI) of middle cerebral artery and umbilical artery which is called cerebro placental ratio as the most sensitive, specific and accurate predictor of adverse perinatal outcome in clinically suspected IUGR Pregnancies.Methods: 50 clinically suspected IUGR Pregnancies attending antenatal clinics Muzaffarnagar Medical College and Hospital, Muzaffarnagar were subjected to Doppler ultrasound evaluation Doppler velocity wave form of umbilical artery and fetal middle cerebral artery were obtained. Pulsatility index ratio of MCA and umbilical artery (cerebro placental ratio) was evaluated in each case. Abnormal ratio is defined as CPR<1.08 considered as cut of value. Ratio was coo related clinically with perinatal outcome.Results: Out of 50 antenatal cases, 63% neonates had birth weight <2.5 kg. There were 6 IUD’S and 44 live births, 9 neonates were admitted to NICU, 7 neonates had 5 min. APGAR score <7 and 13 neonates were born by emergency CS. Of the 6 IUDS, 4 cases had reversal of blood flow umbilical artery and 2 cases had absent diastolic flow. In all cases of reversal Diastolic flow, IUD occurred within 7 days of diagnosis. Conclusions: CPR is the most sensitive, specific and accurate parameter in prediction of adverse perinatal outcome and thus can help in decreasing perinatal mortality.
